ah, sorry I was unclear. I meant the general text format

src/rust/engine/logging/src/logger.rs

,

pub fn log_from_python(
    &self,
    message: &str,
    python_level: u64,
    target: &str,
  ) -> Result<(), String> {
    python_level.try_into().map(|level: PythonLogLevel| {
      log!(target: target, level.into(), "{}", message);
    })
  }

so, that formatting is something the

log!

macro in the rust logigng crate is doing?

yes, and apparently the log level is controlling the

[INFO]

formatting when apparently that's supposed to be a debug log? not sure about that

oh, I flipped that deliberately in my local copy of the code, just to force it to log something to test something unrelated
